Carrying loads — whether you're hauling groceries, moving boxes, or doing a loaded ruck march — is a surprisingly effective full-body workout. This calculator estimates the calories you burn during 25 minutes of carrying based on your weight, the load you're carrying, and the intensity of your effort.
Using the standard MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities, the tool applies a simple formula: calories = MET × weight (kg) × duration (hours). You can choose between light, moderate, and vigorous carrying, and even adjust for the weight of your load to get a more personalized estimate.
Whether you're tracking daily activity, planning a fitness routine, or just curious about your energy expenditure, this calculator gives you a quick, reliable number. It's perfect for hikers, movers, parents, and anyone who wants to understand the calorie cost of everyday carrying tasks.

How to Use This Tool
Enter your body weight (in kg or lb) and, optionally, the weight of the load you're carrying. Select the intensity that best matches your activity: light (e.g., carrying a few grocery bags), moderate (e.g., carrying a 15–20 lb backpack), or vigorous (e.g., carrying heavy boxes up stairs). Click Calculate to see your estimated calorie burn for 25 minutes. The result includes a breakdown showing the MET value used, your total weight (body + load), and the formula applied.
If you don't know your exact load, you can leave it at 0 — the calculator will still give a reasonable estimate based on your body weight alone. Use the quick-fill buttons to try common scenarios.
How It Works
The calculation uses the MET (Metabolic Equivalent of Task) system from the Compendium of Physical Activities. MET values represent the ratio of energy expended during an activity compared to resting metabolism. For carrying, the Compendium lists values such as:
- Light carrying (e.g., carrying small items): ~3.5 METs
- Moderate carrying (e.g., carrying 15–20 lb): ~4.5 METs
- Vigorous carrying (e.g., carrying heavy loads upstairs): ~6.0 METs
The formula is: Calories = MET × weight (kg) × duration (hours). Here, weight includes both your body weight and the load, since carrying extra weight increases energy expenditure. For 25 minutes, duration is 25/60 = 0.42 hours.
Worked Examples
Example 1: A 70 kg person carries a 10 kg backpack at moderate intensity.
Total weight = 80 kg. MET = 4.5. Calories = 4.5 × 80 × 0.42 = 151.2 kcal.
Example 2: A 150 lb person (68 kg) carries no load at light intensity.
Total weight = 68 kg. MET = 3.5. Calories = 3.5 × 68 × 0.42 = 99.96 kcal.
Example 3: A 200 lb person (90.7 kg) carries a 30 lb load (13.6 kg) vigorously.
Total weight = 104.3 kg. MET = 6.0. Calories = 6.0 × 104.3 × 0.42 = 262.8 kcal.
Tips & Best Practices
- For the most accurate estimate, weigh yourself and your load on a scale. Guessing can lead to errors of 20% or more.
- If you're carrying intermittently (e.g., carrying groceries from the car to the door), the actual time spent carrying may be less than 25 minutes. Adjust the duration accordingly.
- Carrying on uneven terrain or stairs increases intensity — choose the vigorous option in those cases.
- Remember that MET values are averages; individual metabolism, fitness level, and technique can cause variation.
Factors Affecting Accuracy
MET values are derived from laboratory studies and represent group averages. Your actual calorie burn depends on several factors:
- Body composition: Muscle burns more calories than fat at rest and during activity.
- Fitness level: Trained individuals may be more efficient, burning slightly fewer calories for the same task.
- Load distribution: A well-fitted backpack may be less taxing than an awkwardly held box.
- Speed and terrain: Walking faster or uphill increases MET.
Use this calculator as a planning tool, not a medical measurement. For personalized advice, consult a healthcare professional.
Frequently Asked Questions
Q: Does carrying really burn that many calories?
A: Yes, carrying adds resistance to your movement, increasing energy expenditure. A 25-minute moderate carry can burn 100–200 kcal depending on your weight and load.
Q: Can I use this for rucking?
A: Absolutely. Rucking (walking with a weighted backpack) is a popular form of carrying exercise. Use the moderate or vigorous intensity setting based on your pace and load.
Q: How does this compare to walking?
A: Walking at a moderate pace burns about 3.5–4 METs, similar to light carrying. Adding a load increases the MET value, so carrying burns more calories than unloaded walking.
Q: Is it safe to carry heavy loads?
A: Start with lighter loads and gradually increase. Use proper posture and take breaks. If you have back or joint issues, consult a professional before starting a carrying routine.
